The Malpassi/FSE unit IS set at 3.2bar as a base setting if you get one from Trent Saab in the UK. As the unit retards pressure in the same non- linear way as it increases it ( 1:1.7) if you set the base pressure too low ( 2.5 bar) the fuel pressure will be very low when you connect up the vacuum pipe and can cause idle problems. A 3 bar setting with the vac hose disconnected will give a 2 bar pressure with the vac hose connected.
